Here are a few small cleanups of unused function parameters. The first five just drop the unused parameters. These are all trivially correct, since otherwise the compiler would complain. But I tried to make sure that dropping was the right thing in each (rather than it being a bug where the parameter should have been used). The final one just uses the parameters for an assertion, following a pattern we've used before. I'll try to cc the individual authors for each patch.
